v This' invention relates to the manufacture ofshoes' and is hereinvset forth by way of illustration with particular reference to its use in the removal of surplus materialfrom the peripheries of the heel-seats of the soles of shoes to prepare them for the attachment of Wood heels, though in some of its aspects the invention is not limited to suchuse.

In the manufacture of shoes to which Wood and some other kinds of heels Aarerto be attached, the heel-seat surface of thek sole of each shoe is fitted for the attachment of a heel by removing surplus material from its lperiphery to form aconvex surface substantially complemental to the concave attaching surface of the heel so that a firm attachment of the heel may be secured and the upper edge of the heel may be brought into close engagement with the shoe upper. This heel-seat fitting operation was long performed by hand, but of recent years has been doneincreasingly by machines.y

-One object of the present invention is tov provide an improved heel-seat Y- fitting machine of simple and rugged. construction vby means of which a good quality of work may be done at high speed without requiring eX- cessive'skill on the part of the operative.

-A feature of the invention, considered in its machine aspect, resides in a novel machine organizationfor trimming a piece of work, such as a piece of shoe stock, to form a` convex surface thereon. As disclosed herein theinvention is .embodied in a heelseat fitting machiner provided with a cutter having a cuttingedge curvedabout an axis extending, during the trimming of the sides of the heel-seat portion of the sole of a shoe,

inthe general direction of the length of the shoe As illustrated, this cutter is formed as a hollow cylinder with a circular cutting edge at an open end thereof and rotates abouta horizontal a-Xis. Cooperating with v this cutter :is a movable work support, together with suitable mechanism arranged to causev relative movement of the cutter and the Work support so that the heel end of a shoe may be presented to the cutting edge at the open end of the cutter and moved inside the cylinder to cause the cutter to trimy surplus material from the horseshoe-shaped areal about the periphery of the heel-seat ofv the sole of the shoe. With ysuch an organiza-k tion the cutter may be madeY effectivey first to trim tne rear end of theheel-seat and then progressively to remove surplus material simultaneously from both sidesof the heel-seat forwardly to a point adjacent to the heel-breast line.

In heel-seat fitting itis common .to distort thel peripheral portion of the heel-seat of the sole so asto position it awayrfrom the upper during the-trimming operation, thereby protecting the upper and allowing the trimming cut to produce a bevel the outerr edge of which is a substantial distance from the edge of the heel-seat of the sole.` Following this practice, and in accordance With other fea# tures of the invention, novel means are pro'- 'vided to distort the sole, said means being arranged to engage the randvcrease at the rear of the shoe, distorting the rear end of the heel-seat of the sole away from the shoe upper.v The distorting means then follows around the heel-seat, acting progressively at opposed points to lift the edge of `the sole somewhat away from the upper priorto the action of the cutter vas the shoe and cutter are given a relativemovement of translation.

It isa further object ofthe invention to provide a heel-seat iitting machine organiza` tion including an improved work support constructed and arranged to facilitate the presentation ofk a shoe to a trimming cutter', for example to a cylindrical cutter such Aas is described above. I havev found that the proper presentation. of a shoe to a hollow, cylindrical cutter, in such a manner as to cause said cutter to bevel first the rearv end of the sole and then the sides of the heel-seat of the sole, preferably involves relative movement between the cutter and the shoe successively in a plurality of different directions, the shoe being presented first in a ter acts upon the side edges of the heel-Seau l" Accordingly, another feature of the inven- .tion resides in a heel-seat fitting machine organization including novel shoe-supporting and presenting mechanism by means of which the shoe is given both a tilting movement and a movement of translation automatically tov present the shoe to the cutter for the heel-seat fitting operation. As illustrated, this mechanism embodies a pivotally supported runway in which there is mounted a slidable carrier upon which the shoe support itself is pivotally mounted, said carrier being arranged for movement along the runway in a path toward and awayfrom the trimming cutter to cause the heel end of the shoe to be projected into the hollow, cylindrical cutter as the latter operates upon the heel-seat of the shoe.

When shoes are to be fitted for Cuban heels, for example, the bevel cuts along the sides of the heel-seat are terminated in transverse shoulders against which the breast of the heel may be abutted. A further feature of the invention resides in a cutter mounted for pivotal movement about the axis of the trimming cutter so that it may be moved transversely of the sole to cut upright shoulders therein adjacent to the heel-breast line. Such a cutter may preferably be operatorcontrolled.

When shoes are to be fitted for other types of heels, such` as Louis heels for example, the bevel cuts along the sides of the heel-seat may be brought out to the tread surface of the sole without forming any abrupt shoulder. Moreover, it frequently is desired to make a transverse cut adjacent to the heelbreast line extending forwardly and downwardly into the sole of the shoe to form a stiff tongue or flap beneath which the over-V hanging breast of a Louis heel may be placed. To these ends still other features of the invention reside in an organization whereby the machine may be caused to operate in such a fashion that it will fit the heel-seat in accordance with either or both of these methods.` Accordingly, the illustrated machine is arranged so that the shoe may be tilted in various ways as it is moved in a generally horizontal direction to present the heel end of the shoe within the cutter, thereby to cause the cutter to produce the desired effect upon the sole.

In another of its aspects the invention comprises a novel method of trimming surplus material from a work piece to produce a convexly curved surface thereon, said method being characterized by the introduction of the work piece into the interior of a hollow, substantially cylindrical, rotating knife, and causing mutual engagement of and relative movement between the work piece and the edge of the knife, thereby causing the knife to form a convexly curved surface upon the work piece.

In still another aspect the invention consists in the provision of an improved method of heel-seat littinfr according to which the rear end of a shoe is introduced into the interior of a hollow, substantially cylindrical, rotating knife and relative movement of the shoe and knife in the general direction of the aXis of rotation of the knife is produced to bring the sole and the cutting edge' of the knife into mutual engagement. rlhis relative movement may be continued along a plural-ity of angularly related directions to cause material to be removed first from the rear end of the heel-seat and then from a side or simultaneously from opposite sides of the heel-seat.

The trimming away of surplus material is effected, in the use of the illustrated ma-v chine, by means of a hollow7 skiving cutter 20 of the ring knife type which is mounted for rotation. about ai horizontal axis as best shown in Fig. 1. This rotary skiving cutter 20 is formed with a hollow cylindrical blade having at one end a sharpened circular cutting edge 22 and is provided with a transverse flange 24 by meansy of which it is. attached to and supported upon a sleeve 26 mounted for rotation in uprights 28 and 30 formed upon a base memberl 32. Power applied from any suitable source to a driving pulley 34 causes continuous rotation ot' the cutter during the operation of the machine. It will be noted that the cylindrical cutter 20 is of such a size that the heel end of a shoe may readily be inserted bodily within the cutter. The cutter is caused to skive and bevel the side edges of the sole adjacent to the heel-seat and to this end its diameter is such that it will cut the desired bevel simultaneously upon opposite sides of the sole forming a convexly curved surface, as indicated in Fig. 7 where the dotted circle indicates the position of the edge 22 of the cutter.

In order that these bevel cuts may be so formedy upon the sole that they will be disposed a substantial distance inwardly from the periphery of the heel-seat oit' the shoe, relatively narrow rand crease engaging iinrovided which have sharpened ends beveled in two directions, as indicated in Figs. 7 and 9, and tapered lengthwise at 44, as shown in Fig. 8, so that theyA may be presented in the rand crease of the slice adjacent to the exe treme rear end thereof and will bepushed apart during the movement of the shoe into engagement vwith thev cutter and will continue to follow along the rand crease at the sides of the heel-seat. To this end the iingers 40 and 42 are mounted in the arms 46 and 48 extending laterally and forwardly from supporting plates 50 and 52 (Figs. 1 and 7 which are pivotally mounted upon the vsleeve 26 of the cutter and are guided between retaining plates 54 and 56 sepa,- rated by spacing members 58 and secured 1in turn to la sleeve, 60 surrounding the sleeve 26 within the upright 80. :These supporting plates are individually connected by means of links 62, 63, to a slide 64 which is disposed below said plates and which is mounted upona stud 66 in the basel 32 and is provided with a spring 68 urging said slide downwardly to press the rand crease engaging fingers resiliently into the creases of the shoe. The fingers 40 and 42 are lpivoted in hollow transverse extensions 47 and 49`extending inwardly from the arms 46 and 48. In order that the fingers may be selfadjustinv and normally retained in a horizontal plane, flat springs 70 are provided (Figs. 8 and 9) attached to the extensions 47 and 49 and bearing uponilats formed upon theL outer ends `of the` fingers themselves. Pins 72 in the extensions 47 and 49 engaging grooves in the fingersr 40 and 42 aided by vshoulders 74 (Fig. 8) upon the fingersk outward movementl prevent inward or through. the bearings in the extensions 47 and 49 asv the fingers are-operated, progres- -sively to distort the periphery of the sole.

The action of the fingers 40 and 42 in distorting the edges of the sole is `assisted by a holddownillustrated as a pressure roll l8.0

supported just ahead of the cutting edge 22 in the adjustable outer part 82 of an arm 84 which is pivoted upon a pin 86 extending between brackets 88 formed upon theV upright 80. A. spring 90 (Fig. 1) vurges the roll into contact with the sole of the shoe to hold the sole firmly against the last for the action of cutter .20. The downward movement of roll is limited by. means of a stop screw 92 adjustable in arm 84 and bearing against a iixed portion of the ma.-

chine forward of the pivot pin 86. Adjust .ment of the length of arm 84 is provided for by a clamp bolt 94 the parts 82 and 84.

YThe presentation of a shoe tothe action of the cutters is greatly facilitated in the present construction by the construction and arrangement of the work support, the parts of which are Abest illustrated in Figs. 1,2, 3 and 6. This support 'comprises a runway 100, pivotally mounted at one end on a transverse pin y'102 upon the base 82'. This vrunway is'grooved (Figs. 2 and 6) forthe reception of a bifurcated slide or carrier comprising separated plates 104v and 106,

which are joined at 109 (see Fig. 3) forV l simultaneous movement and are provided with rearwardly sloping uprights 108 and 110 between which there is lcarried a shoe support 112 (Figs. 1 and 2). This support 112 is provided with lateral hangers 114 by passing through a slot in Vll() means of whichv it is pivotally mounted between the uprights 108 and 110. Plates 105 and 107 igs. 2 and 6) retain the. bifurcated slide in the groove of the runway 100. The shoe support 112 is provided at its rear -end witha last pin 116, upon which the last 118 of a shoe 120, the sole 122 of which is to be fitted, may be mounted, and the toe of said shoe is supported by means of a toe support 124 vertically adjustable by means of its threaded shank 126 in the forward end of the shoe support 112. This toe support 124 is U-shaped, as shown in Fig. 2, and is provided with a saddle formed by a transverse leather strap 128 secured at its ends by means of clamping bolts 130. The tilting of the shoe upon the carrier is effected b means of a bell-crank lever 132 having a b1furcated upper end 134 which is slotted for engagement with a transverse pivot pin 136. This bell-crank lever 132 is pivotally supported at 138 between two uprights 140 and 142, which are also carried upon the side plates 104 and 106, respectively, of the slidable support or carrier in the runway 100. The lower forked end 144 of the bell-crank lever 132 engages a transverse pin carried by lugs 145 (Fig. 1) extending upwardly from the top of an actuating slide 150 .(Figs. 1, 2 and 4). This actuating slide 150 is provided with teeth 151 upon its lower surface for engagement with a pinion 152 carried upon a transverse shaft 154 in the runway 100 and extending laterally therefrom for engagement with and operation by a detachable crank 156. By means of'this crank, movement of the actuating slide 150 lengthwise of the runway 100 may be imparted, and this movement, by suitable controlling mechanism to be described, causes a tilting movement of the shoe support 112 through the bell-crank lever 132 and a movement of translation of the shoe support through the divided slide 104 and 106. lln order that the turning of the crank 156 may move the parts so as to cause the desired sequence of operations, spring-pressed latches 160 and 162 are mounted inside the slide member 104, as shown in Figs. 2 and 3, and the actuating slide 150 is provided with notches 164 and 166 for engagement by said latches,Y respectively. The latches in the slide 104 are spring-pressed to cause engagement of their inner ends with the slide 150 while their outer ends Contact with the inner surface of the runway which is grooved, as indicated at 168, to allow said latches 'to be pressed outwardly to release the latches from the notches 164, 166 when the slide 104 is in such a position with respect to the runway 100 that the'latches are opposite said groove. Movement of the slide 104 in the runway is limited by a stop pin 169 which may occupy either of two holes in the runway 100 (Figs. 1 and At the beginning of the operation of the machine, when it is desired to mount a shoe upon the shoe support, the slides are moved to their forward positions, as indicated in Fig. 12, so that the actua-ting slide 150 is locked tothe slide 104, and consequently to Leoaose the slide 106 because slides 104 and 106 are permanently connected at 109, kby means of the forward latch 160 which has engaged the notch 164 in the slide 150 and is held therein by contact with the side of the runway 100. ln this position the shoe support will be tilted, as indicated in Fig. 13, because of the relative positions of the slides and their consequent effect upon the bellcrank lever 132. Here it will be easy to mount the lasted shoe upon the shoe support 112, after which the crank 156 may be operated to move the actuating slide and with it the slides carrying the shoe support 112 to bring the rotating cutter 20 into engagement with the rear end of the sole in the rand crease between the sole and the upper, this action being facilitated by theprior engagement with the shoe of the cooperating rand crease engaging fingers 40 and v42, in the position illustrated in Fig. 8, where their wedge-shaped portions, as shown in Fig. 9,

tend to tilt up the rear end of the sole and,V

facilitate the entrance of the edge 22 of the trimming cutter into the rand crease to remove surplus material from and reduce the end of the heel-seat. At this time the slides will have advanced to the position illustrated in Fig. 14, and the shoe will be in engagement with the cutter as shown in Fig. 15. lt will be noted that in this position the actuating slide 150 is about to be released from the slidable support 104 because the forward latch 160 has come to a position opposite the forward end of groove 163. Continued movement of the crank 156 will therefore impart a movement to the actuating slide which will not be communicated to the slidable support 104 because the latter is held by the positive engagement of the latches 160, 162 with the ends of the groove 163 but this moven'ient will cause tilting of the shoe about an axis at an angle to the axis of rotation of the knife through the operation of the bell-crank lever 132 to bring it to 'the position illustrated in Fig. 17, where it will be seen that the heel-seat portion 170 of the shoe is substantially in a horizontal plane, the cutter having entered the sole sufficiently to cut through the sole to form the bevel 172 (Figs. 5 and 11) at the rear end of the heel-seat. At this time the notch 166 in the actuating slide 150 has been brought to a position opposite to the rear latch 162 which has remained at the rear extremity of the groove 166 and is ready to be spring pressed into the notch 166. This again locks together the actuating slide 150 and the slidable support 104 for the shoe support 112 s that the shoe support may be given a movement of translation toward the trimming cutter 20 to cause the latter to cut along the sides of the heel-seat to form the beveled portions 174 simultaneously at opposite sides of the Lsoaose heel-seat, creating a horseshoe-shaped flap 176 (Fig. 4) of surplus material. The movement'last mentioned, considering any single point in the heel-seat, will be along Va rectilinear path or direction angularlyv the position indicatedin Fig. 18, withl the heel end of the shoe inside the hollow cut-ter 20. In this position theslides 104 and 150 lare locked together. At this stage the trimming cutter 20 has advanced over the heelseat and, by reason of its cylindrical form, it has .simultaneously cut away the surplus material at the opposite sides of the heelseat as thev edges of the sole, were progressively`V distorted and lifted up away from the upper by the action of the rand crease engaging t`1ngers-40y and 42. The latter, by reason of their tapered edges 44 and lsharpened ends, as shown in Fig. 7, have moved along in the Arand crease as the shoe has been moved into the machine and have passed around. the curved portions at the rear end of the heel-seat to lift up all portionsof theedge of the sole the bettery to protect the upper and to bring said edge portions of the sole into proper position for the action of the trimming cutter. lIn this operation they are `assisted by the pressure roll 80, which vbears against the sole of,l the shoe slightly in advance of'said finders.

lThis part ofxthe operation completed, it is necessary to finish the removal ofthe horseshoe-shaped portion 176 and to make cuts adjacent to the heel breast line in accordance with the type yof heel to be applied to the shoe. If a heel of the Cuban type is to be used, thencommonly the surplus material 17 6 will be removed by transverse cuts adjacent tothe heel-breast line forming Ashoulders 178 (Fi 5) against vwhich the breast ofthe heel may be abutted. For this operation the machine [is provided with an auxiliary cutter or knife blade 180 mounted at the outer end of `an arm 182 `just forward of the cutting edge 22 of the trimming cutter 20, and `provision isvmade for swinging said arm lto carry-the knife 180 acrossthe sole to make the transverse cuts forming .shoulders 17,8. v,To this end the arm `182 is formed as an extension from a diskshaped plate 184 mounted to rotate (see Fig. 1) upon an enlarged portion 61 of the sleeve 60 andvhaving a flange186 surrounding thevv outer edge of the retaining plate 54 which is secured tov said enlarged portion `61 by suitable screws. Movement ofthe plate 184 and the knife 180 carried thereby may be imparted by means of an operator controlled device in the form of a treadle rod 188 connected to the flange 186, The plate 184 isbiased to its initial position. by means of a spring 190. n

If, on the ether hand, a Louis heel or-a heel of that type is to be applied to theshoe, it may be preferred so to operate the 'machine that beveled cuts 192 and 1S-}4,'(Fig. 10) may be formed at the sides of the" heelseat 170 adjacent to the heel-breast :"line. With this style of heel t-he thin overhanging breast of the heel overlies the sole ofthe shoe from which there has been skived a covering Hap 196 which, after the applica-v tion of the heel, is cemented to its breast surface; With the same type of 'heel' it sometimes is desired to make an additional cut forwardly and downwardly into the sole of the shoe adjacentlto the heel-b1east`line to form an additional stiff flap or tongue 198, which isvthe double lia of United States Letters Pat-ent No. 1,52 ,963, granted February 24, 1925, upon the application of Prec and Henne. y

To facilitate these Louis heels, the machine is provided-with mechanism for tilting the runway '.100 in order to change the path of movement of the shoe so that by givingthe shoe supportan additional movement of translation withthe runway 100 tilted downwardly the trimming cutter 20 may be caused to emerge from.k the sole in the position illustrated in Fig. 21- to form the beveled cuts 192 and 194. For this purpose the runway is supported at its under side upon a cam 202 (Figs. 1,21v and 23) carried upon a transverse shaft 204 passing through bearings 206 formed in the base 32 of the machine and attached at one end to an operator controlled tilting member 208 which is grooved at 210 for the reception of an adjustable connecting block 212 ,having a hand screw 214 by means of which said connecting block 212 may be positioned at 'any desired point in the length Vof `the groove 210 and especially at one end or the other thereof. The treadle rod 216 is attached to the connecting block 212 andis normally heldin upper position kby means of a spring 218. In this position, asfit is held yby the spring 218,- the cam 202v isy so dis- Y posed with respect to the runway 100V that said runwayv is held substantially parallel to the'base 32 yof the machine. 'If now the connecting member 212 is clamped by means latter 'operations' for 208 in thisdirection is limited by means of an adjustable stop screw 220 carried by a brldOe 222 secured to the outer sideV of the lbase 32. It will be recalled that .the movement of the slidablesupport in the-'runway 100 toward the rear of the machine is limited by a stop pin 169.y Whenthe machine is to be operated, as shown in Fig. 2l, however, to cause the cutter to make the bevels 192 and 194, this pin is withdrawn and placed in its rearmost position as in Fig. l, so that an additional movement of translation may be imparted to the slides by means of the actuating crank 156 to bring them to the osition shown in Fig. 20.

If? in addition, it is desired to form the double flap 198 of Fig. l1, then the hand wheel 214 must be loosened and the connecting member 212 moved to the other end of the groove 210, after which a combined depression of the treadle rod 216 and the actuation of the crank 156 will be effective to move the parts into the position illustrated in Fig. 22 and to tilt the runway to a position limited by the engagement of stop screw 224 upon the bridge 222 with the other end of the actuating member 208 as shown vin Fig. 23. Obviously, it will be necessary, between the two operations indicated in the diagrams of Figs. 2l and 23, to bring the shoe support forward by means of a reverse actuation of the crank 156 in order that the trimming cutter 20 may reenter the sole at a point to the rear of the heel-breast line in order to form the double flap'198.
